Unfortunately, I'm not bringing ideas, just more quarks. I've worked around most of the problems discussed here by hand coding and holding my tongue just right when I save. I've been able to use links in a 'composed web page' and have those linked pages appear within a frame with the moodle header still visible. Wikipedia pages, however, will not cooperate. Unless I select 'new window' (or hand code 'blank') it will eliminate moodle when it loads in the same window. In other words, it leaves moodle and the back button will not return it to moodle (unless you pull down the 'back' history and manually select the last moodle page). I don't want to have all these links open in new windows because users will end up with a gazillion windows open.
I learned hand coding so long ago that my memory doesn't cooperate much either, but it's there code that will open one new window and let you reuse that? Or does anyone know a way around Wikipedia's window control issues?
